If you need electronic image versions to trace into a CC3+ map, North Carolina Maps may help, if you haven't bookmarked their site already, that is!

I think the snag is that volcanoes tend to be, and make, their own mountains, so they'd typically affect how the mountains nearby look as well - that is, they'd blend into one another completely. Right now, they look a bit too much dropped-in-from-space.

That can work in some cases, where the volcanic mountain is quite isolated especially - the classic example might be Olympus Mons on Mars, which has a vast cliff almost all around its outer base.

However here, the symbols look rather out of place currently in both versions.

There is a mass of fractal entities on that sheet Cal, which is making things run VERY slowly overall, and it may be this which is causing you so much grief.

This is just from a very quick check through, however, and I'm sure Sue's assessment will be far more useful!

Dragging this topic back into the light, as I recently discovered this book was reprinted in all its glory in 2024 (the original is dated 2018). It's an astonishing, and beautifully-illustrated, collection of essays by various authors. It's been on the shelves in my local bookshop since at least December apparently, though I only saw it in detail for the first time today.

Thanks very much folks!

@Royal Scribe: Since the map needed both a substantial overland area as well as underground features, and I really wanted to work in colour again after a long spell of black-and-white mapping, Sue's collection of "Dark & Creepy Forest Lands" just seemed the perfect fit. I've played around with a number of cliff-mapping options before too, and this meant I could finally try out this option for the first time as well. Redrawing the cliff shadows was a bit trickier, because I wasn't holding with the default option, but hopefully the archway shadows over the four entrances to the underground areas don't look to bad (to my eye anyway!).

@Don Anderson Jr.: Yeah, I spent a while tinkering with those pillar shadows. Ordinarily, all the underground features come with such wall shadows as standard (if of varying length, and sometimes strength), but like you, I'm not keen to have them for most things in such circumstances, especially in this case, where there are overground shadows too. Usually - as here - I change them to glows so the light seems to be, very loosely, coming from overhead.

However, the ceiling in the Great Temple is quite high (30 ft, 9 m, with a gentle barrel-vaulting; most other places are only one-third that in the subterranean sections), and the pillars reach right up to it (as will be explained in the notes for the map with the Atlas version), so I wanted to try to hint-at something of that here. Of course, in the circumstances the Great Temple walls ought to have similar shadows, but that starts to look even messier. I played around with glows for a while, but that didn't looked right (the things stopped looking like pillars at all in most cases), so this was the "least worst" option, with watered-down wall shadows.

Ultimately, I felt they added the right note at hinting towards the central importance and size of this main chamber, so held with that.
